I used to get ridiculed for speaking properly, even by my own family, I was actually accused of being a snob (although sometimes more rude terms were used.) because I did not use contractions or slang most of my childhood and teen years, but it was just the way I spoke.
I spent most of my early life interacting primarily with adults, and a LOT of that time was with my great grandmother and great grandfather who are Scottish and Welsh. I think that this is why I do not have a lot of conversations outside of work or the Egg Thief, I have tried to adopt the "normal" phraseology, but it just gets all mixed up to the point that nothing sounds quite right to my ear.
